Corrosion-resistant stainless steel concrete beam

Abstract

The invention discloses an anti-corrosion stainless steel concrete beam. The concrete beam comprises a beam body, wherein the beam body comprises an anti-corrosion concrete structure and a stainless steel bar structure, the stainless steel bar structure is arranged in the anti-corrosion concrete structure, a supporting structure is arranged on the lower portion of the anti-corrosion concrete structure, the supporting structure involves a supporting steel plate, sealant and a rubber pad, an embedding groove is formed in the lower portion of the anti-corrosion concrete structure, the internal ofthe embedding groove is coated with a layer of stainless steel plate, the supporting steel plate is embedded in the embedding groove, the rubber pad is arranged under the supporting steel plate in acushioned mode, and the rubber pad and the supporting steel plate are fixed through expansion screws. The beam structure has good corrosion resistance, the service life of the structure can be prolonged, and meanwhile, the maintenance cost of the structure within the service life can be reduced, when concrete is in a strong alkali environment, a passivation layer can be formed on the surface of the steel bar, mounting and fixing are convenient, and the structure is firm.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a corrosion-resistant stainless steel concrete beam. Background technique [0002] The Achilles' heel of steel bars in reinforced concrete structures is their poor corrosion resistance, which not only reduces the service life of the structure but also leads to serious degradation of the structure's functions. Due to its good anti-corrosion ability, stainless steel reinforcement can increase the service life of the structure, and at the same time reduce the maintenance cost of the structure during its service life. When the concrete is in a strong alkali environment, a purified layer will be formed on the surface of the reinforcement, which is not easy to rot. However, since the concrete material is a hydrophilic material, and it is easy to produce small cracks and voids in the process of winding and daily use, the moisture and chloride in the air will contact the...

AI Technical Summary

Problems solved by technology

However, since the concrete material is a hydrophilic material, and it is easy to produce small cracks and voids during the winding and daily use process, the moisture and chloride in the air will contact the steel bars through the cracks, resulting in corrosion.

The rusting of the steel bar will increase the volume of the steel bar and expand the concrete, which will lead to further cracking or even spalling of the concrete, resulting in a decrease in the durability of the structure. Therefore, it is necessary to invent a corrosion-resistant stainless steel concrete beam to solve the above problems
